(for any
error)
(1) Outputs a contact signal (SPDT) when a protective function has been
activated to stop the motor.
Contact rating:
250 VAC, 0.3A, cos
φ
= 0.3, 48 VDC, 0.5A
(2) Any one of output signals assigned to terminals [Y1] and [Y2] can also
be assigned to this relay contact to use it for signal output.
(3) Switching of the normal/negative logic output is applicable to the
following two contact output modes: "Between terminals [30A] and
[30C] is closed (excited) for ON signal output (Active ON)" or "Between
terminals [30A] and [30C] is open (non-excited) for ON signal output
(Active OFF).

Standard
RJ-45
connector
(1) Used to connect the inverter with the keypad. The inverter supplies
the power to the keypad through the pins specified below. The
extension cable for remote operation also uses wires connected to
these pins for supplying the keypad power.
(2) Remove the keypad from the standard RJ-45 connector, and connect
the RS-485 communications cable to control the inverter through the
PC or PLC (Programmable Logic Controller). Refer to Section 2.3.7,
"Setting up the slide switches" for setting of the terminating resistor.
Figure 2.20 RJ-45 Connector and its Pin Assignment*
* Pins 1, 2, 7, and 8 are exclusively assigned to power lines for the
standard keypad and multi-function keypad, so do not use those
pins for any other equipment.
• Route the wiring of the control circuit terminals as far from the wiring of the main circuit as
possible. Otherwise electric noise may cause malfunctions.
• Fix the control circuit wires inside the inverter to keep them away from the live parts of the
main circuit (such as the terminal block of the main circuit).
• The RJ-45 connector pin assignment on the FRENIC-Multi series is different from that on
the FVR-E11S series. Do not connect to the keypad of the FVR-E11S series of inverter.
Doing so could damage the internal control circuit.
Mounting the interface printed circuit board (interface PCB)
• Usually, you do not need to remove the interface PCB. However, if you remove the interface
PCB, be sure to mount the interface PCB by putting hooks provided on the interface PCB
into the inverter until you have heard click sound.
